Did 552hp at 1087 ft lbs yesterday on the Jefferson state dyno, about 3 years prior I'd did 571 with stock transmission, same 310 tune file, an OEM turbos. I'm now running river city 59/75, with the same tune an a built trans. What are you guys seeing for rail pressure on the 310 tune? I could a sworn those few years back I was pushing 27k psi, an now my rails are dropping off to 22,600, truck has 90k miles tuned the whole time, Im thinking a weak pump is to blame for my numbers, thoughts? Anywhere else to look?
